Would be great if I can see some of GitHub contributions or languages user use to write code. There are too small info about a person to make decision to accept or decline. But the idea is great. I see this website is a place where I can meet teammate for some hackathon or meet him offline on the conference or some meetup or whatever to collaborate or help with contributing into his project...
